German astronomers have conducted photometric observations of a recently discovered polar known as J1832.4-1627. This object is the first deeply eclipsing stream-fed intermediate polar so far detected. The study was detailed ...
These cosmic ribbons of gas have been left behind by a titanic stellar explosion called a supernova. DEM L249 is thought to be the remnant of a Type 1a supernova, the death of a white dwarf star. White dwarf stars are usually ...
